Delta faces $500 million in lost revenue as result of tech outage last week, CEO says

Delta Air Lines CEO Ed Bastian says the airline is facing $500 million in costs related to a global tech outage last week that disrupted emergency services, communications and thousands of businesses.

Speaking on CNBC, Bastian said Wednesday that the monetary amount represents lost revenue as well as "the tens of millions of dollars per day in compensation and hotels" for the five-day period.

A week ago, CrowdStrike blamed a bug in an update that allowed its cybersecurity systems to push bad data out to millions of customer computers, setting off the global tech outage that grounded flights, took TV broadcasts off air and disrupted banks, hospitals and retailers.
